' To all whom may concern.'

Beit known that I, ,Pinnen PLAN'rrNGA,

a citizen of the [mited Sta-tes, resident of Cleveland, county' of Cuyahoga, and State of Ohio, have invented a new and'usetul Improvement in Coke-vens, of which the following is a specification, the principle of Athe invention being herein explained and the best inode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to coke ovens, and

particularly to coke ovens in which itis necessary or desirable to regulate and control theheating operation. The object ot the invention is to provide af coke oven structure economical of construction andl etlicient l in the performance ot' its function.

The annexed drawings and the following description set 'forth in detail certain means enibodyimg,r my invention, such disclosed means constituting, however, but one o't' the 'various mechanical forms in which the principle. ot' the invention may be employed.

In said annexed drawings:-

Figure l represents a vertical vlongitudinal section of a eolie oven embodyingr my invention. Figs. 2, 3 and 1 represent yertical scc tions taken on the planes indicated by the lines IIs-1I, Hl-II'L respectively. Fig'. l, and IV-IV Fig. 3.

The illustrated embodiment of my invention comprises a plurality of pairs ol parallel regenerators 1, cach including the usual checker-work. `Each of these pairs is composed of two regenerators, a iront regenerator shown at the left ot' Fig. l, ami a rear regenerator shown at the right. Each niember of each pair of regenerators is separated from the other thereof bymeans ot' a center "ertical wall 16. A duct 2 comuumiratesI with the bottom of the front rcfrenerator and afduct with the bottom ot the rear one,

y these ducts alternately acting as outlets l'or Aand ducts 2 and 3.

' the gases ot' combustion to the stack as will be readily understood by those skilled in the art. A distributing' Chamber 4- is 'toi-med beneath each pair ot' regcnerators. as shown in Fig. i, and valves llt are provided t'or controlling conununication between them Each chamber 4 is connected with an air-supply pipe 5. communication through which is controlled by a lsuitable valve 6, as shown in Fig. l.

Communicating directly with the top of the regeneratgis, respectively, are two dis- Specieation of Letters Patent.

tributing chambers 20, and communicating with cach o1 them 1s a pluralityot' upright i intake, ducts 7, the tops of each ot which communicates with two adjacent heatingtlues 8, one in front and one at the rear of each duct 7. A set or series composing a plurality of uptake ducts 7 and heatingtlues S, is placed between the walls adjacent; to the colcing-ehambers 21, the longitudinal dimensions of the latter beingparallel with the longitudinal dimensions oit the regenerators, as will be understood. The lower ends of each series of heatingdlues S communi- Cates, by means ot' openings 9, with an intermediate horizontal heatingdlue or chamber 1t), which extends throughout the length of thc oven above the rcgcnerators and bc,- neath the coking-chamber. The communication through these openings and hence the heating at this zone is regulated by means of suitable valves 15.

Extending` along the upper part of the oven is a plurality of gas supply pipes 22, one ot such pipes being provided 'lor each set ot fines T and S. From these pipes cxtenddownwardly the gas supply ducts 11 'tor supplying' the burners 1Q, the lower ends of which communicates with the upper ends of thc heating-dues 8,1m shown, at which point the gas is mixed with air and burned. Allach gas duct 1l is provided with a valve I8, as shown in Fie, J). whereby the amount of gas admitted Vt'or burning;` may be controlled.

The oven as thus liar described operates as `t'ollo ws ssumine' that the (I irrurtion ot' flow ot the gases: is that indicated by the arrows. air is admitted into thc leftdiand or first regenerator l. into the distributing duct 4- and passes upwardly through the checker-work thereof. becoming heated durincr its passage. This air then passes into the lett-hand chambcr 2t). upwardlv through the ducts i at the top ot' cach ol which it divides and sov passes over into the do\\*n\\'ardly extending' 'heatimr-tlues 8. Before thus passing' down- 10, whence they pass into the right-hand portion ot' the latter through the openings t),

upwardly through the heating-fines 8 which now act as mere outlet dues, then down;

wardly-through the ducts 7 and into the right-hand chamber thence throughthen right-hand or rear regenerator into. the distributing chamber 4: thereof, and thence ont through Vthe 'discharge or exhaust ductll.A

. 'After this operation has taken l'place the required length or' time, Ithe'direction of air andthegases ocombustionis reversed by turning the air into the rear .chamber e and gases is reversed. By 'providing the dam- I pers or valves 15 for controlling communica.

tion between. the heatingfnes 8 and the vlue 10, regulation is provided in a. zone sub- -jected to substantially constant conditions,

and a minimum of ad'jnstii'ig of the valves is 'hence required.

ln 'the above-described operation, it will be noted that unmiXed air is being supplied f Such to'but one-half of the heating-nues' of a series, the other half of the heating-fines acting as outlet ducts for the gases of combustion.. For the purpose of supplying gas to he mixed with the air and to supply the required heat, but one-halfof the ducts l1 need be used during the one operation, and

Y the other half during such operation may 'he closed, if desired. However, in case 'it should be found vdesirable to increase the heating effect of the gaseso combustion, the gastroin the remaining half of the gas snpplying ducts may loe burned at the top of the heating-fines of that portion thereof which is on the outlet side of the apparatus..

`For instance, in the alcove-described'op-L eration, gas from those ducts llfon the left handelde of the figure, that is, on the left of Aa plane passing through -the center of 'the wall 16, is mixed 'with the .air and burned. The gas burners to the right oithis plane may be shut off. lt, however, it is desired to heat the gases of combustion which are passing through those ducts and 8 to the right 'of the abovementioned plane.; gas

from `those ducts 1l` above the right-hand section of the. apparatus may he burned and thus increase the heating effect of these gases of combustion.

From the alcove description `it will he noted that the temperatureof the -gases of combustion may he regulated in 'various degrees'.'

regulation, however, may he further amplified by providing additional gashiirn ing means. These may consist of a plurality of gas pipesl, one for each set of heat -ingfines 7 above eaeh'iegenerator; as shown in '.1', Connected. with eechof Ithese eene i -loipesenre upright burnersf?, onel of the latter being provided for each air-duct 7.

These burners discharge the gas into the lower' ends oit these air-duets 'la at which vpoint such gas maybe' burned orthe purpose of increasing the temperature' `f desired, in this Zone.

i heretofore heen provided in certain types of ove-m ont they have been located at the'to'p oi? the even structure and immediately alcove' the heatinglues. By so locating this flue at the top, the brick 'partitions are mate-- iisilly weakened. Since these partitions form the real' strength of the oven Wall, a material advantage is gained by eliminating Horizontal Adues such as theilue 10 have this weakness and placing the horizontal flue at the bottdn'if, as abovev described.

- This intermediate i practice becomes eirceedingly hot' and'fwhen i it is located' at the top, itisin a position r horizontal .flue in i adjaceifit to. the'A top .ofjtlie colting chamber and hence substantiallyall ofthe gas manufactured in this'coking-chamher mustpass adjacent to and hence comes in cont-attl with, these -exception'ally highly .heated walls of the vhorizontal liie.

This @Seite iii theti'ired in the coking-fchiiinher into carbon and hydrogen, with theieonsequent loss' of valu-1 able hydrocarbons By locating this intermediate flue at the bottoni, however,' it'fwill loe seen thatitsheat may be applied tothe y i `bottom of the charge of coal Where it is most needed and the heated Wal'lstthe inter cokiiig-chainber in which practically neges vhas yet heenornied or at leastfii `little.` The liability of loss "of, liydr'oe ig superheating is therefore-reduced in jairiiii muni.
